DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

It is an object of this invention to provide a toothbrush made hygienic by protecting the bristles of the brush from coming in contact with harmful contaminants, including bacteria, microbes, fungi, protozoan parasites, viral agents, or other contaminants, e.g. fecal contaminants, when the brush is not in use. This object is accomplished by provision of a protective cover that prevents contaminants from settling on the brush bristles when the brush is not in use, and is further accomplished by provision of a closable storage compartment in which the cover is stored while the brush is in use, protecting the cover itself from such contaminants. It is recommended (but not necessary) that the brush head be rinsed in an antiseptic/antibacterial solution (such as Listerine®) prior to placing the cover over the bristles to kill any bacterial/viral agents transferred from the user's mouth. This procedure used in combination with the present invention will result in potential health benefits. Still another related advantage is that the present hygienic toothbrush with cover solves a major health concern in that it also prevents contamination by insects. The common housefly and other disease carrying insects love to frequent bathrooms.

It is another object of this invention to provide the toothbrush with a hollow storage compartment with lid that remains assembled to the toothbrush for hygienically storing the cover when the toothbrush is in use. Because the hollow storage compartment with lid is permanently adjoined to the toothbrush, it is much more likely to be used on a consistent basis. The cover may be protected from coming in contact with harmful contaminants while the brush is in use by placing the cover in the hollow storage compartment and closing the lid. Again, it is recommended (but not necessary) that the cover and hollow storage compartment be rinsed with an antiseptic/antibacterial solution (such as Listerine®) prior to placing the cover in the hollow storage compartment to kill any bacterial/viral agents transferred from the user's mouth. This procedure used in combination with the present invention will result in potential health benefits.

The hygienic toothbrush with cover of the invention is constructed principally of various plastic materials. The cover may include mesh side panels of a fibrous woven or mesh-like plastic material, so as to allow the bristles to dry after use.

As noted, it is an object of the invention to provide a toothbrush with a hollow storage compartment and lid that are assembled to the remainder of the toothbrush. The toothbrush cover is readily maneuvered into the hollow storage compartment in the brush handle for temporary storage during brushing. When the user is finished brushing, the brush cover is similarly readily maneuvered to cover and protect the bristles. An advantage of designing the toothbrush and hollow storage compartment with a lid that is not detached from the toothbrush in use is that the hollow storage compartment will be more likely to be used to hygienically store the cover. Storing the cover, for example, in a separate storage compartment with lid may result in the cover being lost, rendering it ineffective.

It is another object of the inventor to prevent cross contamination between toothbrushes stored in close proximity. Toothbrushes in a conventional toothbrush holder are often in close contact with one another. Even the briefest contact can cause a transmission of harmful contaminants from one brush head to another. A family member that is sick or “coming down with something” can easily contaminate another family member's brush with harmful bacterial or viral agents. The hygienic toothbrush of the invention with hollow storage compartment and lid prevents this contact and therefore prevents the transmission of these agents and illness associated with them.

It is still another object of the invention to produce a hygienic toothbrush that is space efficient. The hygienic toothbrush of the invention, with bristle cover, hollow storage compartment, and lid is constructed in such a way that the cover is spacious enough so that the bristles do not contact the inner surface of the cover when in a closed position, thereby inhibiting bacterial growth, yet is small enough so that it fits within the hollow storage compartment with lid in the handle structure, completely out of the way, when in use brushing a user's teeth.

Other objects, features, and advantages will become obvious to those skilled in the art from the following descriptions and accompanying drawings.

FIGS. 1-9 and 14-16 depict a first embodiment of a toothbrush assembly according to the invention. The toothbrush assembly 5 comprises an elongated toothbrush body 7 having a bristle head BH at one end and a handle H at a second end. The handle H comprises a storage compartment 16 for receiving a bristle cover 12. A lid 45 for covering the hollow storage compartment 16 is operably coupled to handle H. In the embodiment of FIG. 1, a recess 47 is provided adjacent and below the lid 45 for insertion of a user's finger or alternatively a lever to pry open the lid 45. The lid 45 may be provided as a separate element, as shown, or may be formed by the back side 12 d of the cover 12, the cover 12 having an open face 12 b enabling the cover 12 to be placed over the bristles B.

The toothbrush 5 is constructed principally of various plastic materials, while ventilated side panels 12 a of the cover 12 may be constructed of a fibrous woven or mesh plastic material.

In the embodiment of FIGS. 1-9 and 14-16, the toothbrush assembly 5 comprises an elongated connector 14 comprising a first end 37 operably coupled to the elongated toothbrush body 7 at a point between the bristled head BH and the hollow storage compartment 16 and a second end 8 operably coupled to the cover 12, whereby the connector 14 can be moved so as to move cover 12 between a first closed position (as depicted in FIG. 3), in which the cover 12 is disposed over the bristles B to protect them when not in use, and a second open position (depicted in FIG. 4) in which the cover 12 is protected within the storage compartment 16 when the brush 5 is in use. In the embodiment shown, a first end of elongated connector 14 comprises a transverse pin 37 that is received by a snap-fit into a transverse groove 10 in the toothbrush body 7 (see FIGS. 5 and 6), so that the elongated connector 14 can be pivoted about an axis transverse to the direction of elongation of the toothbrush, moving cover 12 between the first and second positions. The connector 14 may be molded as a single piece, including transverse pin 37 and means for attachment to cover 12.

As illustrated in FIG. 1 and in more detail by FIG. 14, the cover 12 is generally box-shaped, including an open face 12 b, porous sides 12 a, solid end panels 12 c, and a solid back panel 12 d, opposite the open face 12 b. The two side panels 12 a are preferably ventilated to allow drying of the bristles after use, by perforations as shown at 11, or by provision of mesh or woven inserts. Ventilation is provided to expose maximum bristle surface area to the air, while minimizing the possibility of contamination of the bristle head BH. The two end panels 12 c are of substantially solid construction, that is, are not ventilated. The back panel 12 d is solid to prevent contaminants from infiltrating, and the opposed face 12 b is open, in order to receive the bristles.

The bristle head BH, bristles B, and cover 12 may have corresponding round, square, pyramidal, rectangular, rhomboid or other appropriate shapes.

FIG. 5 depicts an expanded front elevation view of the elongated connector 14 for operably coupling a cover 12 to the toothbrush body 7 of toothbrush 5 shown in FIG. 1. The elongated connector 14 has a first end formed to define a spine 14 a and a transverse pin 37, and a second end. As above, transverse pin 37 may be a snap-fit into groove 10 in the handle H, permitting elongated connector 14 to be pivoted about an axis transverse to the body of the toothbrush between first and second positions. The second end comprises a bifurcated member 15, having arms 15 a and 15 b, each arm 15 a, 15 b being terminated with an inwardly-extending compression point or nub 20. The nubs 20 may be inserted into holes 12 e in the body of the cover 12 (see FIG. 14) so that the cover 12 is free to rotate through 360 degrees with respect to elongated connector 14. Alternatively, the cover may swivel on a pin or axle running between the arms 15 a and 15 b. This freedom of motion is provided such that the cover can be pivoted so that its open face faces downwardly, toward the interior of the storage compartment, providing a further measure of protection against contaminant intrusion.

In one embodiment, the toothbrush 5 may include an electric powered sonic vibrator 1, for providing brushing motion when one is using the toothbrush 5 to clean one's teeth. This embodiment is discussed further below in connection with FIG. 26.

The hollow storage compartment 16 is defined by a recess in the handle H, sized to receive the cover 12. The hollow storage compartment 16 may have a peripheral recess 39 for receiving a lid 45, as discussed below.

FIG. 2 depicts a top plan view of a lid 45 for a hollow storage compartment 16 of a toothbrush assembly 5. The lid 45 may be molded integrally with a lid arm 33, joining lid arm 33 at point 43, the lid arm 33 ending in a transverse pin 35, which is received by a snap-fit into a groove 31 formed at one end of the hollow storage compartment 16. In this way, the lid can be pivoted between an open position, to allow the cover 12 to be received in compartment 16, and a closed position, so that the cover 12 is protected against contamination when the toothbrush is in use.

The lid 45 also may have a peripheral mortise 49 and 51, as depicted in FIGS. 7 and 8, that cooperates with the peripheral recess around the compartment 16, so that a substantially airtight seal is formed when the lid 45 is placed over the storage compartment 16. The lid 45 may also have compression points or nibs 41 a, 41 b exerting pressure against the recessed rim 39 so that the seal formed when the lid 45 is placed in the recessed rim 39 is essentially complete. The storage compartment 16 is sized to allow insertion of the bifurcated member 15 and the cover 12 so that the lid 45 may close the opening 17.

FIG. 3 depicts a side elevation view of the toothbrush assembly 5 with the cover 12 in a first closed position, in which the open face 12 b of the cover 12 receives the bristled head BH so that the cover 12 protects the bristles B when not in use.

FIG. 4 depicts a side elevation view of the toothbrush assembly 5 in a second open position, where the bristles are exposed for use and the cover 12 is protected within the hollow storage compartment 16.

In both first and second positions, the spine 14 a of elongated connector 14 may lie in a groove 18 running along the surface of the body 7 of the toothbrush 5, so that an exposed surface of the spine 14 a of the elongated connector 14 becomes essentially coplanar with the surface of the body 7 of the toothbrush adjacent to the groove 18.

FIG. 10 depicts an elevation view of a second embodiment of a toothbrush assembly 55 according to the invention. In this embodiment, the toothbrush assembly again comprises a cover 67 for protecting bristles B′ from harmful contaminants, and which is stored in a hollow storage compartment 63 while the brush is in use. As previously, cover 67 may be operably coupled to a single-piece elongated connector 60 having a first end 57 in pivot groove 59 of the toothbrush assembly 55 and a second end 61 operably coupled to the cover 67. In this embodiment, a lid 65 for the storage compartment 63 slides in grooves on opposite sides of the storage compartment rim 68 along the longitudinal axis 94 of the assembly 55. A raised lip 66 on the lid 65 enables a user to more easily apply sliding force to the slidable lid 65 in order to move the slidable lid 65 between open and closed positions.

FIG. 11 depicts an elevation view of the toothbrush assembly 55 in a first position having a cover 67 covering bristles B′ and slidable lid 65 essentially completely sealing the hollow storage compartment 63.

FIG. 12 depicts an elevation view of a further embodiment of a toothbrush assembly 70, shown with a bristle cover 72 covering brush head BH′. In this embodiment, lid 82 is hinged on an axis orthogonal to the longitudinal axis 104 of the assembly 70, that is, transverse to the body of the toothbrush, allowing it to be pivoted between a closed position, in which it covers the cover 72 when in hollow storage compartment 81, and an open position, allowing cover 72 to be disposed in storage compartment 81. A recess 74 is provided to enable a user to exert opening force to open the hinged lid 82.

FIG. 13 depicts an elevation view of a further embodiment of a toothbrush assembly 85 according to the invention. In this embodiment, a hinged lid 100 for closing off a hollow storage compartment 95 is again provided, but in this embodiment, lid 100 is operably coupled to a body 91 of the assembly 85 by hinge 97 disposed near the end of the handle. The hinged lid 100 may cover the storage compartment 95 by rotation of the hinged lid 100 about an axis running transverse to the longitudinal axis 124 of the assembly 85. Lid 97 is essentially U-shaped in cross-section, so as to form an essentially complete seal with the body 91 to protect the cover 92 in the storage compartment 95 from harmful contaminants.

As discussed above, FIG. 14 depicts an expanded elevation view of a cover 12 shown in FIG. 1 for a toothbrush assembly 5 having holes 12 e on opposed sides for receiving compression points or nibs 20 of the single-piece elongated connector 14 for permitting rotation of the cover. Alternatively, the cover 12 may be intended to be used separately and independently from the single-piece elongated connector 14 to protect the bristles B from harmful contaminants; that is, although in the preferred embodiment the cover is secured to the elongated connector so that it does not become lost, it is also within the scope of the invention to provide a separate cover that is likewise stored in the storage compartment and protected by the lid while the toothbrush is in use.

FIGS. 15 and 16 depict views along horizontal and vertical axes, respectively, of the cover 12 of the toothbrush assembly 5, as depicted in FIG. 14. The cover 12 may have a recessed lip 12 f and compression points or nibs 13 a, b so that when the cover 12 is placed in the direction of the arrow 4 (as depicted in FIGS. 7-9 with respect to the compartment lid 45) in the recessed rim 39 of the storage compartment 16, an essentially complete seal is formed because the compression points or nibs 13 a, b exert pressure against the recessed rim 39.

FIG. 17 depicts a side elevation view of another embodiment of a toothbrush assembly 200 according to the invention. In this embodiment, the toothbrush assembly again comprises a cover 210 covering bristle head 211 but the assembly 200 does not have a single-piece elongated connector operably coupled to the cover 210. A lid 230 covering a hollow storage compartment 231 may be operably coupled to the hollow storage compartment 231. A recess 235 is provided adjacent and below the lid 230 for insertion of a user's finger or alternatively, a lever to pry open the lid 230. The lid 230 is mechanically and physically attached to a lid arm 240, the lid arm 240 ending in a pivot end 245. The pivot end 245 is operably coupled to a groove 250 of the hollow storage compartment 231. Accordingly, the cover 210 is movable between a first position wherein an open face of the cover 210 faces the bristled head 211, so that the cover 210 is disposed over the bristles 213 to protect them when not in use, and a second position wherein the cover 210 is protected within the hollow storage compartment 231 when the brush 200 is in use. As the lid 230 is operably coupled to the hollow storage compartment 231, it is less likely to be lost.

Thus, according to the invention, a method for hygienically cleaning the teeth of a person according to the invention comprises the steps of: providing a toothbrush assembly 5, 55, 70, 85, or 200, wherein the toothbrush assembly 5, 55, 70, 85, or 200 comprises an elongated toothbrush body 7, 91, or 220, having a bristle head BH, BH′, or 211 at one end and a handle H at a second end, the handle H comprising a hollow storage compartment 16, 63, 81, 95, or 231, the hollow storage compartment 16, 63, 81, 95, or 231, comprising a lid 45, 65, 82, 100, or 230 wherein the lid 45, 65, 82, 100, or 230 is operably coupled to the hollow storage compartment 16, 63, 81, 95, or 231; covering the bristles B, B′, and 213, when the toothbrush assembly 5, 55, 70, 85, or 200 is not in use, with a cover 12 or 210 having an open face enabling the cover 12 or 210 to be placed over the bristles B, B′, or 213 to protect them from microbial, viral, or other airborne contaminants, and sealing the cover 12 or 210 in the hollow storage compartment 16, 63, 81, 95, or 231 when the toothbrush assembly 5, 55, 70, 85, or 200 is in use. Preferably, the cover 12 or 210 is cleaned to remove any microbial, viral, or other airborne contaminants before sealing it in the hollow storage compartment 16, 63, 81, 95, or 231.

FIGS. 18-23 show generally a further embodiment of a toothbrush according to the invention, in which the connector to which the bristle cover is secured pivots to the toothbrush about an axis perpendicular to the surface of the toothbrush in which the storage compartment is formed, as compared to the embodiments discussed above, in which the connector pivots about a transverse axis, and wherein the storage compartment is closed by a cover member pivoted to the body of the toothbrush near the end of the handle portion thereof. Several variants on this embodiment are shown by FIGS. 18-23. One advantage of this design is that the open face of the bristle cover will face the bottom of the storage compartment without the necessity of allowing the cover to pivot with respect to the elongated connector, as in other embodiments.

FIG. 18 shows an embodiment where the bristle cover would be moved from covering the bristles when not in use to the storage compartment when in use by lifting the brush cover off the bristles and rotating the elongated connector about an axis perpendicular to the surface of the toothbrush extending between the bristle head and handle, so as to place the brush cover in the storage compartment. FIG. 19 shows the same embodiment but illustrates the elongated connector/bristle cover in a “mid-way” position to make the movement more clear. This may be implemented by provision of a simple pivot mechanism allowing the elongated connector with bristle protector to pivot 180 degrees (in either direction, clockwise or counterclockwise) about an axis perpendicular to the toothbrush body, so as to move the cover into the storage compartment. For example, the pivot mechanism can be implemented by providing a pin configured as a split pin with an enlarged head on the end of the elongated connector, which is snap-fit into a corresponding bore in the body of the toothbrush. The pivot joint can be made sufficiently loose to allow the bristle cover to be lifted off the bristles, or the elongated connector can be flexed to allow this movement. The joint is designed so that the elongated connector and bristle cover are retained by the body of the toothbrush, encouraging their use.

FIG. 20 shows a somewhat different embodiment, in which the pivot connection between the body of the toothbrush and the elongated connector comprises a ball and socket joint, with a ball on one of the connector and body and a socket on the other. The joint is designed so that elongated connector with bristle protector can rotate 360 degrees about an axis generally perpendicular to the surface of the body of the toothbrush, and to some degree out of the plane including the surface of the toothbrush, and so that the elongated connector and brush cover are retained, encouraging their use.

Thus, FIG. 18 depicts a perspective view of a toothbrush 300 having a movable elongated connector 320 to which a bristle cover 310 is secured, and a bristle head 310 and bristles 314 that run orthogonally to the plane of the bristle head 310, a storage compartment 319 and a hinged lid 313. The toothbrush 300 includes a joint 317 allowing the elongated connector to be moved with respect to the body. The joint may comprise an expandable opening in one of the elongated connector and body formed by the ends of deformable finger members, so as to be deformed to receive a spherical member in the other and thereafter retain it. Alternatively, the joint may comprise a bore in one or other of the elongated connector and body for receiving a pin having a head in the form of a split ball, so that the ball is compressed upon insertion into the corresponding bore and thereafter retained, allowing the elongated connector 320 to pivot.

In another aspect of the invention, FIG. 18 depicts a recess 362 running along a perimeter of the cavity 330 of the storage compartment 319. As illustrated in FIG. 18, compression members 371 are disposed around a periphery of the replacable lid 313 which may be snapped into the recess 362 to secure the lid in the closed position

As shown in FIG. 19, the elongated connector 320 is movable between a first position P₁, in which the protective bristle head cover 332 covers the toothbrush bristles 314, and a second position P₂ in which the protective bristle head cover 332 is stored in a cavity 330 of the storage compartment 319. Nub(s) 305, 315, or any appropriate compression fitting, extend in a perpendicular direction from the first surface 318 of the elongated toothbrush body 321 so as to grip the cover and secure it in position over the bristles. The replacable lid 313, depicted in FIG. 18, may be operably coupled to the first surface 318 by hinge 335, as discussed above in connection with other embodiments, or by another appropriate joining device.

In the embodiment of FIGS. 18-20, the toothbrush 300 comprises an elongated toothbrush body 321, having first and second ends 360, 370 and a first surface 318 thereon. The elongated toothbrush body 321 comprises a bristle head 310 operably coupled to the first surface 318 of the elongated toothbrush body 321 at the first end 370 of the elongated toothbrush body 321.

One advantage of the C-clip design shown is that they space the cover from the bottom of storage compartment, allowing drainage and drying to occur.

In a further variant, also shown in FIG. 22, the pivotable coupling 317 at the first end C₁ of the elongated connector 320 includes a spherically shaped member 334 that compressibly fits into an expandable opening 317 in the elongated toothbrush body 321, so that the first end C₁ of the elongated connector 320 is pivotable between the first P₁ and second P₂ positions. As previously, only sides 380, as depicted in FIG. 20, of the protective bristle cover 332 that are parallel to the bristles 314 of the bristle head 310 are porous.

FIG. 23 depicts a side elevation view of the toothbrush 300. As shown, a replacable lid 313 is pivotably coupled to the first surface 318 of the elongated toothbrush body 321 so as to fit essentially flush with the first surface 318 when the lid 313 is closed, covering the cavity 330 of the storage compartment 319, so that the inside environment of the storage compartment 319 is effectively sealed. FIG. 23 illustrates that the replacable lid 313 may open or close in the direction of the arrow 352 when the elongated connector and protective bristle cover 332 are in the storage compartment 319. The lid 313 could likewise be pivotably attached to either side of the toothbrush body. An opening indicated generally at 372 to the outside environment may also be provided, to allow ventilation of the compartment or for better drainage and drying out of the storage compartment.

In each embodiment, the protective bristle cover 332 and the elongated connector 320, or the entire toothbrush 300 are preferably treated with an antibacterial solution. The antibacterial solution may be an aqueous solution of from about 0.01 to about 30 percent by weight hydrogen peroxide in water or isopropanol. Alternatively, it may be a commercial mouthwash/disinfectant, silver-containing composite chemical or any other suitable antimicrobial.

FIG. 19 depicts an embodiment of the invention, in which a portion of the first surface 318 of the elongated toothbrush body 321 that faces the opening 340 of the protective bristle cover 332 is formed to comprise at least one nub(s) 305, 315 that run in the orthogonal direction with respect to the first surface 318, while an edge 385 of the protective bristle cover 332 that faces the first surface 318 of the elongated toothbrush body 321 is resiliently deformable, so that the expandable edge forms a releasable compression snap-fit over the at least one nub(s) 305, 315 when the protective bristle cover 332 is in the first position P₁.

The invention also includes a method of protecting the bristles 314 of a toothbrush 300 in which an elongated toothbrush body 321, having first and second ends 370, 360, and a first surface 314, thereon is first provided. The toothbrush 300 comprises a bristle head 310 operably coupled to the first surface 318 of the elongated toothbrush body 321 at the first end 370 of the elongated toothbrush body 321. The toothbrush 300 comprises an opening 337 in the first surface 318 of the elongated toothbrush body 320 at the second end 360 of the elongated toothbrush body 321. The opening 317 is an entrance of a storage compartment 319 in the second end of the elongated toothbrush body 321. A volume of the cavity 330 of the storage compartment 319 is defined by lateral walls 323 and a bottom 325. The bottom 325 of the storage compartment 319 has a second surface 327 thereon. The toothbrush also comprises a protective bristle cover 332 having an open face 340 enabling the protective bristle cover 332 to be placed over the bristles 314. An elongated connector 320 is also provided, having a first end C₁ pivoted to the toothbrush body 321 between the bristled head 310 and the opening 317, and a second end C₂ operably coupled to the protective bristle cover 332, so that the protective bristle cover 332 is movable between a first position P₁ and a second position P₂. In the first position P₁, the open face 340 of the protective bristle cover 332 faces the bristled head 310 and encloses the bristles 314 to protect them when not in use. The open face 340 of the protective bristle cover 332 faces the second surface 327 of the bottom 325 of the storage compartment 319 in the second position P₂.

Thus, in practice of the method of the invention, the first end C1 of the elongated connector 320 is pivoted radially to move the protective bristle cover 332 from the first position P₁ to the second position P₂. A user of the toothbrush may lift the protective bristle cover away from the bristle head of the elongated toothbrush body by flexing the second end of the elongated connector and pivoting the second end of the elongated connector to the second position. The method may also comprise a step of treating only the protective bristle cover and the elongated connector or the entire toothbrush 300 with an antibacterial/antimicrobial solution. The antibacterial/antimicrobial solution may be an aqueous solution of from about 0.01 to about 30 percent by weight hydrogen peroxide in water or isopropanol or a silver-containing antibacterial/antimicrobial solution.

In an embodiment of the method of the invention, the first end of the elongated connector pivots radially between about 0° and 360° when the protective bristle cover is moved from the first position to the second position and returned to the first position. Depending on the constructional details of the toothbrush, the elongated connector is pivoted about an axis transverse to the direction of elongation of the toothbrush body, or about an axis that is generally perpendicular thereto.

In a further aspect of the method of the invention, in an embodiment of the toothbrush wherein the elongated connector is pivoted about an axis transverse to the body of the toothbrush, the bristle cover is pivoted about the end of the elongated connector, so that the open face of the cover faces the bottom of the storage compartment.

FIGS. 24-26 show further variants within the scope of the invention. FIGS. 24 and 25 relate to further improvements in the bristle cover, and FIG. 26 to an integrated system for powering several additional components.

Thus, in FIGS. 24 and 25, the bristle cover 402 is provided with lid 402 that may be integrally molded therewith, along with living hinges 404—that is, members of reduced cross-sectional area, so as to define hinging points. As shown by FIG. 25, the lid 402 can be snapped over the cover 400, enclosing the bristles for further protection. Also shown schematically in FIG. 25 is a source 406 of sterilizing ultraviolet (UV) radiation, comprising a power supply 408, a switch 410, and UV emitting lamp(s) 412. As is well-known, providing a source of UV in close proximity to the bristles will be effective in destroying bacteria and the like.

FIG. 26 shows an integrated system for use of the toothbrush of the invention, comprising a UV source 406 as discussed immediately above and an ultrasonic vibrator 414, as mentioned above in connection with FIG. 1. These electrical devices will require power, the ultrasonic vibrator when the brush is in use and the UV source when the cover is replaced over the bristles after brushing. In order to avoid the use of power cords, preferably the ultrasonic vibrator 414 is powered by batteries 416 in the body of the toothbrush, connected thereto by conductors 415. When the toothbrush is replaced in a base station 418, contacts 420 in the toothbrush and 422 in the base station 418 mate, completing a circuit comprising well-known battery charging circuitry in the base station 418 for charging batteries 416. Additional contacts supply power to the UV source 406, typically for a short period of time after each replacement of the toothbrush in the base station 418.

The elongated connector and other parts of the toothbrush of the invention are preferably molded of a somewhat flexible plastic material, such as low or high density polyethylene (PE), low or high density polypropylene (PP), or polyvinylchloride (PVC).
